Abstract: In an active antenna array, when a few radiating elements doesn’t work due to some problem. Then the entire radiation pattern gets distorted, mostly due to increased SLL. In this paper, Genetic Algorithm is implemented and compared with Particle Swarm Optimization for linear array synthesis for far field side lobe notch using amplitude only to get the desired radiation pattern with specified SLL. Genetic Algorithm gives optimal solution of the problem than PSO. Numerical results are presented to show the effectiveness of both optimization techniques.
